How is dust removed from the instrument panels in control systems?
Thread Content
As production progressed, some problems emerged. Once, the main control card of the system failed suddenly. Fortunately, it was redundant, so production was not affected. After removing it, a large amount of dust was found inside; it was cleaned with a brush, and after reinserting it, everything worked normally. One can handle it in this way; what to do if there’s too much? How do your on-site control systems remove dust? Feel free to join the discussion.
1. Keep the control room clean at all times; personnel must wear shoe covers or change into slippers when entering and leaving； 2. Doors and windows must be closed, and cable entry holes should be sealed with explosion-proof putty ； Take other dust prevention measures as well ； 3. Regularly clean the cabinet, including removing dust from the dust covers, using a vacuum cleaner to clean the interior of the cabinet, and employing a small brush to eliminate dust in hard-to-reach areas ；
Especially in the newly built factories, there is a lot of dust; our unit uses vacuum cleaners along with handheld blowers!
Control rooms these days are usually well-designed. Here, when there is downtime for maintenance, we use vacuum cleaners to remove dust from inside and outside the cabinets, then use hair dryers to clear the dust inside them; we also take out each component one by one to clean it. On normal days, we simply keep the control room clean
If it’s fully sealed during design, there shouldn’t be this problem, right? I’m working on this as well; all the windows that were reserved originally have been canceled~
1. The initial design of the cabinet spaces is very important. 2 It is most important to maintain good hygiene; clean the fan and filters regularly. 3. Use a blower combined with a vacuum cleaner; anti-static measures are necessary. It’s absolutely forbidden to use such devices for dust removal while the machine is running. If it’s really necessary, submit a report and ask your supervisor to assign someone to oversee the process – it’s very risky to do this while the machine is in operation, otherwise you’ll regret it. 4. In particularly dirty areas, introduce dry instrument air into the cabinets to maintain positive pressure ventilation.
The control rooms are generally sealed, and air conditioners are installed to regulate the temperature. Each terminal is protected by a cover, and the connectors are placed inside control cabinets that come equipped with cooling fans. Apart from regular cleaning, the cabinets and terminals are cleaned thoroughly during major maintenance tasks. The connectors never require manual dust removal; such cleaning is only carried out by the manufacturer during inspections, and no accidents have ever occurred as a result of dust buildup. Therefore, it is very important to keep the control room airtight.
1. The control room can have the dust removed using a vacuum cleaner, with the help of a brush. 2. For outdoor use, instrument air can be considered
1. The control room should be designed to be airtight, with no air leaks. 2. The inlet must be sealed; this is very important, as dust enters mainly through here. 3. Always use a vacuum cleaner for cleaning; do not use a hair dryer. 4. A soft brush can only clean the surface. 5. Currently, DCS modules are quite durable, with good protection for their components, so there’s no need to worry too much.
